Our kitchen floor was in need of something (repair, replacement, rejuvenation?). This being the do-it-yourself age, we took ourselves to the nearest big box home store, and picked out a lovely laminate flooring in a pattern that looks like tile. The ads and the instructions all make it sound like a pretty simple project. We brought it home and set to work. Immediately, we ran into a problem (Fig. 1). Our breakfast nook is in an octagonal shape. This means no matter which wall we started on, we immediately had to tackle an angle cut. Problem: How do you measure an included angle with a protector, when that angle is between two solid walls?
